Election over, so US, China agree to make unenforceable long term commitment with no consequences

JoNova (Australia)
Now that the mid-term elections are over in the US,  Obama is free to announce the climate commitments that voters didn’t need to hear. (I did say this would happen.) It’s a “landmark” agreement and a “gamechanger”, but no one can point out what  happens if either country doesn’t stick to its agreement.
The end-point of this grand theater of intent and glorious promises is Paris 2015."
